Detailed Description

A2A (Agent-to-Agent) JSON-RPC client over Streamable HTTP.

Implements the JSON-RPC 2.0 binding of the A2A protocol — see https://a2a-protocol.org/latest/specification/. Methods supported in this version:

• message/send (sync)
• tasks/get
• tasks/cancel
• AgentCard discovery via GET /.well-known/agent-card.json

Streaming (message/stream, SSE-framed tasks/resubscribe) is not implemented in v1; the awaitable returns once the server reports a terminal TaskState.
